Spectrophotometric Estimation of Total Phenolic Content and Antioxidant Capacity of Molasses and Vinasses Generated from the Sugarcane Industry

To identify a possible use for some agroindustrial wastes generated from the sugarcane industry, we evaluated the antioxidant capacity of B and C molasses and vinasses from the sugar and bioethanol production processes. Molasses and vinasses were characterized by physicochemical methods. Subsequently, the samples were diluted in distilled water at five concentrations to obtain...

Assessment of By-product Valorisation in a Swedish Wheat-Based Biorefinery

Biorefineries are examples of industries striving towards a circular and bio-based economy through valorising natural raw materials to a spectrum of products. This is a resource-efficient process which also decreases overall environmental impact, as the products from a biorefinery can replace fossil-based products such as plastics or fuels. To become even more resource efficient...

After collecting the branches, the raw materials were characterized in matters of...

Storage of Food Waste: Variations of Physical–Chemical Characteristics and Consequences on Biomethane Potential

Food waste (FW) storage influences its physical–chemical characteristics and anaerobic digestion (AD) performance. In this work we present the results of two weeks long experiment where two types of FW were stored in dedicated cells (10 L and 300 L). Air was evenly flushed on the top surface of the substrates and then analyzed to identify and quantify possible gaseous emissions...

Effect of Some Process Parameters on the Main Properties of Activated Carbon Produced from Peat in a Lab-Scale Process

Activated carbons (ACs) are widely used in different industrial processes as adsorbents for pollutant removal or as catalytic material support. The parameters and methods of activation can vary, and they affect the final characteristics of ACs, e.g., specific surface area, pore size distribution, and surface functional groups. The results of this study show that microporosity and...

An Assessment of Contaminants in UK Road-Verge Biomass and the Implications for Use as Anaerobic Digestion Feedstock

Biomass from harvested road-verge herbage has potential value as a feedstock for anaerobic digestion (AD) energy plants. However, the proximity to road traffic related pollution sources introduces the possibility of contamination by potentially toxic elements and polycyclic aromatic hydrocarbons. Potential sources of pollution from road traffic emissions are identified and the...

Performance of Liquids from Slow Pyrolysis and Hydrothermal Carbonization in Plant Protection

The feasibility of thermochemical biomass conversion technologies can be improved if value-added applications for all fractions can be developed.

Application of NMR Spectroscopy and Conventional Analytical Methods for the Assessment of Wastewater from Food Industry

Before wastewater (WW) can be emitted into the municipal treatments plants, its organic matter content has to be assessed and found to comply with legislations. The chemical oxygen demand (COD) and total organic carbon (TOC) are among the most commonly used methods for such analysis. However, volatile organic compounds (VOC) present in the WW might hinder a correct organic matter...
